Sprawling Nor'easter still bringing heavy snow, damaging coastal floods

By: Dr. Jeff Masters , 4:15 PM GMT on March 08, 2013

It's not often that a Nor'easter centered more than 600 miles out to sea brings heavy snow and and major coastal flooding to New England, but Winter Storm Saturn is a one-of-a-kind. The massive storm, which was centered about 600 miles east-southeast of New York City at 7 am EST, sprawls out over a huge area of ocean more than 1000 miles across. While the central pressure of 988 mb is not exceptionally low for a Nor'easter, the sheer size of the storm is allowing Saturn to pile up a formidable storm surge, which hammered the coast of Eastern Massachusetts during the Friday morning high tide cycle, causing severe erosion, widespread street flooding, and damage to roads and houses. Snowfall amounts as high as 18" have fallen in Massachusetts (in West Walpole), and a band of moderate snow has set up along an arc from New York City to Boston. The big storm has dumped 6+" of snow on seventeen states this week, from North Dakota to Massachusetts. The deepest snows fell in the Appalachian Mountains of western Virginia and eastern West Virginia, where a number of locations received over twenty inches. The top snow-getter was Franklin, West Virginia, with 24".

Moderate to major coastal flooding in Massachusetts
The island of Nantucket, MA, which is south of Cape Cod and thus the land area closest to the center of WInter Storm Saturn, has received the worst pounding from the storm's wind and water. The island has observed wind gusts greater than 40 mph every single hour since 6 pm Wednesday evening, and will probably continue to so so until late Friday afternoon (thanks to Eric Fisher for this stat.) A storm surge of 3' hit Nantucket Island on both Thursday and Friday. The storm tide--the height of the water above the high tide mark--reached 2.63' during the Friday morning high tide, and 2.57' during the Thursday morning high tide cycle. These heights beat out the Blizzard of 1978 for 5th highest Nantucket water level since records began in 1965. Only Nor'easters in 1991, 2013 (Nemo), 1992, and 1987 brought higher water levels to Nantucket. Boston was too far to the north of Winter Storm Saturn to receive a top-ten storm tide; the storm surge water level peaked at 2.62' above the high tide mark during the Friday morning high tide, well short of the 3.43' needed to crack Boston's top-ten list.

Our Winter Storm Saturn Section has more on the storm. You can also track current storm surge levels using our wundermap with the storm surge layer turned on.

Join me in Austin, TX on Monday for "Climate Change and the Individual"
I'll be in Austin, Texas on Monday March 11, where I'll be speaking at a panel discussion on climate change that the public is invited to (it's free.) The event is at Bourbon Girl, 212 East 6th Street, 2:30 - 3:30 pm. On stage with me will be David Kenny, CEO of The Weather Channel, and Peter Glatzer and Adrian Grenier, co-founders of SHFT.com. Adrian is the star of the HBO TV series, Entourage. SHFT.com's mission is to convey a more sustainable approach to the way we live through video, design, art and culture. The event is part of "SHFT@Austin", which runs from 10:30 am - 6 pm at Bourbon Girl. The event features a Green Gadget Lab, SHFT's Year on the Road Photo Gallery, in-car app demos in Ford electric cars, and some of The Weather Channel's latest innovations.


Wunderground's climate change blogger Dr. Ricky Rood has a very detailed article in the Washington Post on what it would take for the U.S. to catch up to the European ECMWF group in forecasting skill: "the benefit of additional money can be important, but the impact will be patchy. To be the best in forecasting, the U.S. must face the underlying issues of fragmentation and provide the U.S. organizations responsible for weather forecasting a stable environment in which to function. "

Now, two hours later, the emergency vehicles have pulled back somewhat, and are allowing cars onto either end of the stretch of beaches. The middle beach, full of rocks, which the waves cast onto the roadway, is still closed at this time.

The SPC has added 5% tornado probabilities (and accordingly a slight risk) across central Nebraska and north-central Kansas. This is northeast of the main low, where storms have access to steep lapse rates and marginal instability.

I hope everybody has a nice Saturday. A bit dusty in Japan though ...


A yellow haze settles over Osaka as dust from China and Mongolia blows into town. | KYODO

Sandstorms from northern China and Mongolia are forecast to reach Tokyo this weekend, according to the Japan Meteorological Agency.

Yellow desert dust from China’s northwestern provinces and Mongolia will reach Tokyo at about 3 a.m. Saturday and remain until Sunday morning, according to the agency’s website. Visibility in the Japanese capital will be reduced to 10 km from 40 km at normal levels, the agency said.

The sandstorm, which reached the southern island of Kyushu around noon today, will coincide with graduation ceremonies of some Tokyo schools and universities scheduled to be held Saturday. Tokyo is forecast to be fine and sunny tomorrow, with temperatures expected to reach a maximum of 17 degrees.

Measurements of PM2.5, fine airborne particulates that pose the largest health risks, are not likely to rise significantly due to the sandstorms, Takahisa Goto, an official at the environment ministry said by phone today. Japan’s environment ministry last week said local authorities should issue warnings when concentrations rise to an average of 70 micrograms per cubic meter per hour.

Japan considers PM2.5 readings of 35 micrograms per cubic meter to be safe.

Tropical Cyclone Outlook
16:00 PM RET March 9 2013
=================================

Area of Disturbed Weather southeast of the Chagos Archipelagos:

The suspect area monitored for few days remains badly organized. Convection is still very
fluctuating. Last visible satellite pictures depict a small vortex near 14S 78.5E, totally exposed at about 250 NM northwest of the main convective activity. Mean sea level pressure is estimated at 1003hPa and winds are in the 15-20 knots range in the northern semi-circle, and reach 30 knots, very locally 35 knots in the southern semi-circle by gradient effect with the subtropical high heights. Environmental conditions are unfavorable, with poor monsoon inflow and moderate to strong northwestern upper level vertical wind shear.

For the next 12 to 24 hours, the system is forecast to move slowly eastward. On and after, it is expected to recurve westward within the low level trade-ward flow. On this track, environmental conditions are expected to degrade (weakening monsoon inflow and strengthening of the upper level vertical wind shear at the beginning of the forecast period). System is expected to fill up on and after Monday within the trade flow.

For the next 72 hours, potential for the development of a tropical depression is poor.

SPECIAL WEATHER STATEMENT ISSUED BY THE BAHAMAS DEPARTMENT OF METEOROLOGY FRIDAY 8TH MARCH, 2013 AT 5PM EDT

A deepening low pressure center off the Carolina Coast is generating moderate to dangerous large swell which will propagate southward during the next seven days.

Moderate to Heavy swells have begun bombarding the coastline of the more eastern islands of the Bahamas Chain including the Turks and Caicos Islands.

These Dangerous swells which could exceed 22 feet during its peak on Sunday will result in Sea Spray and over-topping water, particularly around Long Wharf, Go-Slow Bend, Saunders Beach, areas in the vicinity of the Cave, West Bay Street, Eastern New Providence, the Glass Window Bridge in Eleuthera and other areas throughout the archipelago vulnerable to sea swells.

For those who think love of winter and surfing are contradictory:



Surf’s Up On Lake Superior
By Dan Kraker March 9,2012
From WBUR's Only A Game

Excerpt: Bob Tema, a Honolulu native moved to Minnesota more than two decades ago to study graphic design. After living there a couple years, he wondered… could he surf Lake Superior?

After a few years exploring the shore, he discovered there’s some excellent surfing on Lake Superior. When he first started 15 years ago it was just him and a buddy. Now he estimates about 50 surfers ply the winter waves. He says surfing scenes have popped up around the Great Lakes – from Sheboygan, Wis., to Marquette, Mich., — but the premier spot is on Lake Superior, at a place called Stony Point. But the best surf arrives when it’s coldest, when fall and winter storms kick up high winds, big waves and often sub-zero temperatures.

“On those really cold days your eyelids will sometimes get stuck, freeze shut for a bit, you have to kind of pry them open,” Tema said.

The big waves are also intermittent. They might only happen every few weeks. So Tema’s founded the Lake Superior Surf Club with a website where diehards can monitor wave and weather conditions.


Rest of the story and audio here.

Chief, Marine and Coastal Services Branch

Subject: NWS Transitioning from Deterministic To Probabilistic
Storm Surge Forecasts effective with the
2013 Hurricane Season

Effective with the 2013 hurricane season and thereafter, the NWS
will no longer provide deterministic Sea, Lake, and Overland
Flooding from Hurricanes (SLOSH) model output during tropical
cyclones in an unofficial manner.

The American Meteorological Society and the National Academies of
Science have endorsed greater use of probabilistic forecasts by
NWS. For several years, the National Hurricane Center (NHC) has
been providing probabilistic storm surge products as part of a
long-term, multiyear NWS effort to improve communications on
storm surge.

SLOSH deterministic guidance was informally provided to some
users over the past several years; however, the deterministic
SLOSH model output has the potential to conflict with the
official NWS forecast for storm surge and to interfere with
evacuation decisions from emergency managers.

RE 342 THRAWST:

Yep, we've got it too. As my other half says, "That's a serious ____ ground sea! No fishing for us for a week or so!"

... High surf advisory remains in effect until 2 PM AST Tuesday...
... Coastal Flood Watch remains in effect from 4 PM AST this
afternoon through Monday afternoon...

A high surf advisory remains in effect until 2 PM AST Tuesday. A
coastal Flood Watch remains in effect from 4 PM AST this
afternoon through Monday afternoon.

* Waves and surf: large swells of 8 to 10 feet this weekend...
building gradually to 12 feet early Monday morning. This will
result in large breaking waves of 12 to 15 feet this weekend...
and up to 18 feet early Monday morning.

* Timing: starting this morning and continue through at least
Tuesday afternoon.

* Impacts: very large breaking waves will create dangerous surf
conditions and frequent rip currents.

* Coastal flooding: beach erosion is possible around the time of
high tide... especially between Sunday evening and Monday
evening.

The times of the next high tide for the following locations are:

Aguadilla harbor: 6:37 PM AST this evening at 1.07 feet.

Arecibo harbor: 6:51 PM AST this evening at 1.17 feet.

San Juan harbor: 7:10 PM AST this evening at 1.17 feet.

Magens Bay St thomas: 6:30 PM AST this evening at 0.41 feet.

Precautionary/preparedness actions...

A high surf advisory means that high surf will affect the local
reefs... beaches and Shoals within the advisory area... producing
dangerous rip currents.

A coastal Flood Watch means that conditions favorable for
flooding are expected to develop. Coastal residents should be
alert for later statements or warnings... and take action to
protect property.
